I wonder if we should use WebLChar here instead of char...  That will make the
call sites uglier, but maybe that's a good idea because its rare that people
want to call this function.

Done. Though it doesn't actually end up doing much since there's the std::string
version. Just the implementation of fromLatin1(const std::string& s) gets ugly.
